How we work

A German enterprise buyer evaluating a SaaS product will typically ask for a signed Auftragsverarbeitungsvertrag and confirmation of EU, often specifically Frankfurt, hosting before a pilot starts, not after a contract is signed. Procurement teams also frequently want a Pflichtenheft-style breakdown of custom modules scoped for their specific rollout.

We build the multi-tenant architecture around those expectations: AVV terms and sub-processor disclosure ready before onboarding, hosting region fixed at the architecture stage, and a German-language admin console and support so the product doesn't read as a translated afterthought. The team works remotely on the multi-tenant platform, with sprint reviews scheduled inside CET/CEST hours.

Market

What buyers in Germany need from this work

The AVV is a prerequisite, not paperwork that follows the deal
German enterprise procurement generally expects a signed Auftragsverarbeitungsvertrag, including sub-processor disclosure, before subscriber data enters the platform. We prepare that documentation as part of onboarding rather than as a legal step bolted onto the end of a sales cycle.
EU hosting is a sales requirement more often than a technical preference
Buyers frequently ask specifically for a Frankfurt hosting region rather than a general EU assurance. We build hosting-region configurability into the multi-tenant architecture at the start, since retrofitting it into a live platform running in a single region is a much larger project.
Enterprise deals often want a Pflichtenheft for custom modules
Where a German enterprise buyer needs custom functionality beyond the core product, they may expect a Pflichtenheft-style technical response describing exactly how it will be built. We produce that documentation as part of scoping the custom module rather than treating it as unusual overhead.
German-language product experience affects adoption, not just optics
A German-language admin console and support channel measurably affects how quickly enterprise users adopt a platform. We build the string and content layer around a locale attribute from the first release so German isn't a partial translation layered onto an English-only product.
Subscription billing needs VAT ID capture for the B2B reverse charge
A German business customer buying from a platform based elsewhere in the EU generally expects the reverse-charge mechanism applied once a valid VAT ID (USt-IdNr) is captured and verified, rather than VAT added to every invoice regardless of B2B status. We build VAT ID capture and validation into billing signup so invoices reflect the correct treatment automatically.
Named EU cloud regions carry more weight than a general assurance
Enterprise procurement increasingly asks for a specific region, AWS's Frankfurt region, Azure's Germany West Central or Germany North, or Google Cloud's Frankfurt region, rather than accepting 'hosted in the EU' as sufficient. We build multi-region support into the architecture so a named region can be offered and verified during procurement.

Compliance we plan for

GDPR and BDSG for subscriber and end-user data
Auftragsverarbeitungsvertrag signed before onboarding customers whose data the platform processes
EU hosting, frequently Frankfurt-region, as a data-residency requirement
European Accessibility Act / BFSG where the platform is a covered digital service

How the engagement runs

We confirm hosting-region and AVV requirements during discovery, since German enterprise procurement typically asks for both before a pilot starts. Development on your SaaS platform runs in sprints with a shared staging environment, and reviews are scheduled inside CET/CEST hours.

Invoicing is in EUR tied to delivery milestones, settled by SEPA transfer, with DATEV-compatible exports available for your finance team. The codebase, Frankfurt-region infrastructure and admin access stay under your control throughout.

FAQ

Frequently asked questions

Do we need a signed AVV before onboarding German customers onto our SaaS platform?

Generally yes, since your platform will be processing personal data on your customers' behalf, which GDPR Article 28 requires a data processing agreement for. We prepare AVV terms, including sub-processor disclosure, as part of onboarding.

Can our SaaS platform host German customer data specifically in Frankfurt?

Yes. We build hosting-region configurability into the multi-tenant architecture at the start, so a Frankfurt or other EU region can be offered as an option for customers who require it as part of procurement.

Do German enterprise buyers expect a Pflichtenheft for custom SaaS modules?

Often, yes, particularly for larger deals involving custom functionality. We produce a Pflichtenheft-style technical response describing how a custom module will be built, which then serves as the reference for acceptance criteria.

Can you add DATEV-compatible export to our SaaS platform's billing module?

Yes. We scope DATEV-compatible export formats for invoice and transaction data so a German customer's accounting team can ingest it without a manual conversion step.

Does BFSG accessibility apply to our SaaS admin console or only to a customer-facing portal?

It depends on whether the platform counts as a covered digital service under the BFSG's scope; a customer-facing portal for a covered sector like banking is more likely to be caught than an internal admin console used only by your own staff. We scope which parts of the product need WCAG-aligned accessibility during discovery rather than applying, or skipping, the requirement uniformly.

How important is a fully German-language admin console for enterprise adoption?

It has a measurable effect on how quickly German enterprise users adopt a platform, beyond what a partial translation provides. We build the locale layer to support a complete German admin experience rather than translating only the marketing pages.

Can our SaaS billing apply the B2B reverse charge for German customers automatically?

Yes. We build VAT ID (USt-IdNr) capture and validation into billing signup so a verified business customer gets the reverse-charge treatment automatically, rather than VAT being added to every invoice regardless of B2B status.

Can our platform offer a named EU cloud region instead of a general 'hosted in the EU' claim?

Yes. We build multi-region support into the architecture so a specific region, AWS's Frankfurt region or Azure's Germany West Central region among them, can be offered and verified during procurement rather than relying on a general assurance.
